Answer:
1.
The slope is 2
The y-intercept is -10
equation: y = 2x - 10
2.
Slope: 2.5
y-intercept: 1
Equation: y = 2.4x + 1
Step-by-step explanation:
1.
x y
2 12
4 16
8 24
10 28
from 12 to 16 you add 4
from 2 to 4 you add 2
y/x = 4/2 = 2
The slope is 2
The y-intercept is -10
equation: y = 2x - 10
I got the y-intercept because I went from 12 to 0 which is -12, and then 2 - 12 and it's -10

x y
5 4
20 10
30 14
35 16
from 4 to 10, u add 6
from 5 to 20 you add 15
y/x = 15/6 = 2.5
Slope: 2.5
y-intercept: 1
Equation: y = 2.4x + 1
I got the y-intercept because I went from 4 to 0 which is -4, and 5 - 4 is 1.

Find the sides marked with letters:
X = ? W = ?
Answers
Answer:
x = 4
w = 1.5
Step-by-step explanation:
Here, we want to find the value of x
We use the principle of similar triangles here
We have these as;
(x + 2)/6 = x/4
4(x + 2) = 6x
4x + 8 = 6x
6x - 4x = 8
2x = 8
x = 8/2
x = 4
We proceed to get w;
3+w/6 = 3/4
4(3 + w) = 6(3)
12 + 4w = 18
4w = 18-12
4w = 6
w = 6/4
w = 1.5
There were 41 tickets sold for an event. Tickets for children cost $1.50 and
tickets for adults cost $2.00. Total receipts for the event were $73.50. How
many of each type of ticket were sold?
Answers
Answer:
17 kids 24 adult
Step-by-step explanation:
17+24 = 41
17x1.5=25.5
24x2=48
48+25.5=73.5
For the event , 24 adults and 17 children tickets were sold .
Let :
Number of children ticket = cNumber of adult tickets= aNow we have the equations :
a + c = 41 ____(1)2a + 1.5c = 73.5 ___(2)from (1):
a = 41 - c ___(3substitute (3) into (2)
2(41-c) + 1.5c = 73.5
82 - 2c + 1.5c = 73.5
-0.5c = -8.5
c = 17
From (3)
a = 41 - 17
a = 24
Hence, 24 adults and 17 children tickets were sold .

Sasha hikes into a canyon. She takes a break at the rest stations every 2/3 of a mile she descends.
If she started at sea level and has hiked down to the fourth rest station, what is Sasha’s elevation now?
Select all that apply.
Answers
a. -8/3 miles below sea level.
Sasha started at sea level and has hiked down to the fourth rest station.
Now sea level is 0.
Sasha takes a break at the rest stations every 2/3 of a mile.
This means she is down to 4 rest points means 4 times 2/3
This becomes =
But the answer will be in negative as she is below 0.
So, correct answer is: a. -8/3 miles below sea level.
Other way,
sea level is 0.....so if u go below sea level, u will end up with a negative number...and since she is hiking down, ur answer will be negative. The is a station every 2/3 mile....and if she passed 4 of them....
-2/3 * 4 = - 8/3 <=== her elevation....another answer could have been - 2 2/3, but that is not there
Sasha's elevation will be -8/3 miles below sea level.
What is an expression?The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
Given that Sasha hikes into a canyon. She takes a break at the rest stations every 2/3 of a mile she descends.
Sasha started at sea level and hiked down to the fourth rest station. Now the sea level is 0. Sasha takes a break at the rest stations every 2/3 of a mile.
This means she is down to 4 rest points means 4 times 2/3
This becomes = 4 x ( 2 / 3) = 8 / 3
But the answer will be negative as she is below 0.
Therefore, Sasha's elevation will be -8/3 miles below sea level.

Describe the nature of the roots for the equation 49x2 - 28x + 4 = 0.
A. two real roots
В.
one real root
C.
two complex roots
D.
one complex root
Answers
Answer:
We conclude that 49x² - 28x + 4 = 0 has only one real root.
Thus, option B i.e. one real root is the correct option.
Step-by-step explanation:
Given the equation
49x² - 28x + 4 = 0
comparing with the quadratic equation ax² + bx + c = 0 for x, where a ≠ 0,
here
a = 49, b = -28, c = 4
Determining the discriminant b²-4ac
b²-4ac = (-28)² - 4(49)(4)
= 784 - 784
= 0
It is clear that the discriminant b²-4ac is equal to zero.
i.e.
b²-4ac = 0
We know that if the discriminant b²-4ac = 0, then the quadratic equation has one real root.
Therefore, we conclude that 49x² - 28x + 4 = 0 has only one real root.
Thus, option B i.e. one real root is the correct option.

Option B is correct answer.
Step-by-step explanation:
We need to find the trigonometric ratio Sin X
We know that [tex]Sin X = \frac{Perpendicular}{Hypotenuse}[/tex]
Looking at the figure, we have:
Perpendicular = XY = 24
Base = YZ = 10
Hypotenuse = XZ = 26
Now putting values in the formula and finding value of Sin X
[tex]Sin X = \frac{Perpendicular}{Hypotenuse}\\Sin X =\frac{24}{26}\\Sin X =\frac{12}{13}[/tex]
So, we get [tex]Sin X=\frac{12}{13}[/tex]
Option B is correct answer.

Step-by-step explanation:
3(x + 2)=x + 11
3x + 6=x + 11
2x + 6=11
2x=5
x=2.5
Answer:
x=2.5
Step-by-step explanation:
3(x+2)=x+11 (distribute 3 to x&2)
3x+6=x+11 (then you subtract x from both sides)
2x+6=11 (subtract 6 from both sides)
2x=5 ( divide by 2 on both sides)
x= 2.5

Carlt mowed 2 more lawns than rocco week for 5 weeks. Carlt mowed a total of 18 lawns. How many lawns did Rocco mow each week?
Answers
Answer: 1.6 lawns a week
Step-by-step explanation:
Carlt mowed 2 more lawns than Rocco every week for 5 weeks.
This means that the number of lawns he mowed more than Rocco is:
= 2 * 5
= 10 lawns
If Carlt mowed 18 lawns in those 5 weeks then Rocco mowed:
= 18 - 10
= 8 lawns
Lawns mowed per week by Rocco:
= 8/5
= 1.6 lawns a week
